SeRM is a proprietary golf ball coating that enhances spin at an atomic level. Its molecules are bonded using Moveable Cross-Links that work like microscopic pulleys and ropes, distributing loads evenly among the molecular chains that make up Q-STAR TOUR’s urethane cover. That even distribution of shearing force makes SeRM urethane incredibly elastic. So elastic, in fact, that it expands into your wedge and iron grooves at impact.
That added bite increases friction on all your approach shots. And that extra friction means more spin and more control every time you hit into the green.
